MR. DEYERLEIN S METHOD OF MAKING 

 BRICK, TILES, ETC. 



The machinery by which this process 

 is to be effected, consists of a box, or re- 

 ceptacle, into which clay or other matter 

 is to be put, and also of a plug or forcing 

 instrument, by which the clay is forced 

 out of the receptacle during the operation, 

 through suitable openings in one end of 

 the containing box, which gives the re- 

 spective parts the required shape. The 

 motion or effect is imparted to the forc- 

 ing instrument, by mill-work, or other 

 well known mechanical means; and the 

 articles when made, are received on a 

 proper carriage for conveying them away. 

 Another carriage may also be used for 

 supporting the combined parts of the ap- 

 paratus during the time of working, or 

 for conveying them from place to place 

 when necessary. 



The patentee having described the 

 apparatus generally, and illustrated its 

 several parts by figures, states the 

 process of the operation to the fol- 

 lowing effect. It is necessary to have 

 two or more wheelbarrows, such as before 

 described, for conveying aivay the bricks 

 after they are made, and one of these be- 

 ing hooked on to each muzzle or mouth- 

 piece of the machine, through which the 

 clay is to pass, it will be fit for operation. 

 The clay should not be made so wet as 

 usual. The piston or forcing instrument 

 is first drawn to one end of the box, by 

 means of the wheel-work with which it 

 is connected, and the other part of

the receptacle is then filled with the 

 clay or other materials. The piston being 

 then put in motion, the clay is forced 

 through the orifice in the mouth-piece 

 of the box, and received on the wheel- 

 barrow attached to it for that purpose; 

 having the shape of the opening through 

 which they have passed. If the recepta- 

 cle be a double box, or have a mouth- 

 piece at each end, while this operation is 

 performing, the other end is filled with 

 cla}^, which the returning stroke of the 

 piston forces through the other end, and 

 so on alternately. By this operation the 

 clay will be formed into bars of the size 

 and shape of the openings in the machine; 

 and the person who attends, separates 

 them into the required lengths by a pro- 

 per instrument guided by grooves per- 

 pendicular to the surface of the wheel- 

 barrow; or rather to the axis of the bars. 

 In the apparatus which the patentee has 

 described, each stroke forms seven bars 

 of the breadth and thickness of a brick, 

 but of sufficient length to be cut into 

 four; and by this means every home and 

 out stroke of the machine, fifty-six bricks 

 are produced; and more or less may be 

 obtained at a stroke according to the 

 number of openings in the mouth-piece, 

 and the power of the first mover. Tiles, 

 mouldings, &c., may be made in the same 

 manner, by merely changing the mouth- 

 piece for one adapted to the particular 

 purpose.
